Amy Schumer should be celebrating the release of her new movie, I Feel Pretty, but instead she’s in the hospital to treat a serious kidney infection.

On Friday, April 27, the actress took to Instagram to share why she won’t be at the UK premiere of her new film. “Here’s what I’ve been up to this week,” she wrote alongside a photo of herself in a hospital bed. “I was hospitalized for five days with a horrible kidney infection. I wanted to share this with you because this is sexy as hell but mostly because I was meant to go to London for the opening of I Feel Pretty and my doctors have told me that’s a no go.”

She continued: “I’m really disappointed selfishly to miss this trip because I love London and Europe in general and all the great people (food) there. But I need to put my health first. I am so grateful for all the support the movie is getting. I hope people check it out in England and everywhere else in the world. It’s sweet and fun and you will walk out feeling better. Which is something I hope to feel soon too.”

She also used the post to thank her caretakers, including husband Chris Fischer. “I want to give a big thank you to the doctors, the badass nurses, also my husband whose name is, I want to say, Chris?” she joked. “And my sisters Kimby and Mol who have been by my side the whole time.”

We’re sending good thoughts for a speedy recovery.
